In carrying out my invention, I may make use of an ordinary step ladder1, such as commonly used by workmen engaged in wallpapering. My deviceis adapted to be mount- {m ed upon either the top step of said stepladder as shown or upon any other suitable portion of said step ladderby a bracket mounting means generally indicated at 2. This mounting 2 isadapted to support the wall papering machine suspension means 3 forsuspending the machine 4 or to support said suspending means 3- in analternative position for the positioning of the Wall papering machine 4to perform diflerent papering operations.

The Wall-papering machine proper 4 consists of a pair of end plates 5'and 6 joined together by means of rods 7 which are made integral withsaid end plates by any suitable means. These end plates provide bearings1' in which the various rotatable and movable portions of thewall-papering machine proper are journa-led.

Secured in the lower portion of this wallpapering machine proper 4between the end plates 5 and 6 by rivets, bolts or other suitablefastening means is the paste chamber 8 consisting of an ordinaryrectangular boxlike member as appears most clearly in Figures 5, 6 and7.

For filling this paste box or container 8 with paste I provide asuitable duct 9 extending from one of the end walls of the walI-paperingmachine proper, as shown in this embodiment. This duct 9 limits thecapacity of the paste box 8 to a point 10 coincident with its upperextremity. A suitable door 11 closes this duct against the admission ofextraneous matter and secures the paste in the box. This door 11 may bespringpressed or maintained shut in any other suitable manner, ifdesired.

For the exit of the paste from the paste box when it is desired anoutlet bore 12 may be formed in the opposite end or in the same end ofthe paste box for communication with the similar bore formed in one ofthe end plates to provide a suitable outlet from the paste box. A plug13 engages in this bore for closing the same and preventing emission ofpaste when undesired. This plug 13 may be threadedly engaged with thebore or secured therein by any other suitable fastening means. The bodyportion of this plug is made of any suitable transparent material 14which permits the observation by an operator of the amount of paste inthe box thereby forming a simple and eflicient indicating means for thispurpose.

For cooperation with the wall paper for performing the wall-paperingoperation 'I provide a paste roller 15 which is journaled for rotationin the box by any suit-, able means. In this embodiment however Iillustrate the use of members which I term side plates 16 havingbearings 17 at their sub stantial centers for journaling the ends 18 ofthis paste roller 15. These end plates 16 are connected to the walls ofthe paste'box and are maintained in relatively fixed position by anysuitable means. They are made sufiiciently wide in this showing tocompletely span the space between the end of the roller 15 and the endof the paste box 8 to prevent the insertion of paste or other adhesivematerial utilized in the paste box into said box through said space andto prevent splashing of the paste from said box. It caneasily beunderstood that the use of this space for the insertion of paste mightlead to splashing of paste over parts which should be kept clean at alltimes to insure a successful operation of the machine.

In the upper portion ,of the end plates 5 and 6 bearing slots 19areprovided for adjustably j ournaling a roll 20 upon which the tion alongthe slot 19, as is easily understood.-

Fo'r preventing over-travel aswell as back lash of the wall paperrelative to the roll 20 when the same is withdrawntherejfrom by anoperator, I provide a stationarily positioned roll 23 journaled in theend plates 5 and 6 in any convenient or suitable position relative tothe roll 20. This roll 23 cooperates with a spring pressed orresiliently urged l or pivotally mounted bracket arms 25 and 26 whichare rotatably journaled on the shaft 27. The coil springs 28 and 29secured to the shaft 27 as indicated at 30 and 31 respectiyely cooperateat their opposite extremities with the bracket arms 25 and 26 tonormally u'rge said bracket arms 25 and 26 to press the roller 24 intoengagement with the roller 23. For permitting an operator to adjust theamount of pressure exerted by the roller 24 on the paper between saidroller and the roller 23, I provide a small lever handle 32 which isfixedly secured to the shaft 27 on the outside of either. of the plates5 and 6. This small lever handle 32 is resiliently forced outwardly bymeans of a coil spring 33 engageable between said crank lever and theadjacent end plate. This spring maintains the lever in any adjustedangular position. Suitable stops 34 limit excess movement of the roller24.

For guiding the wall paper through the machineduring the insertionthereof and duringfthe operation I provide a pair of plates 35 and; 36positioned on opposite sides of the path-taken by said wall paper afterit leaves the rollers 23 and 24 and adapted for the reception of saidwall paper therebetween. These guide plates 35 and 36 may be fastenedinjthe end plates of the wall papering machine proper or they may beadjustably secured therein by any suitable means not shown. The platesmay also be formed in any desired fashion to secure the function ofproperly alining the paper during its operation. I have shown one ofthem made in simple rectilinear form while the other 36 has obliqueportions 37 and 38 at its extremities to; engage and assure properalinement of In this construction however the paper for entry into thespace between the l plates. The operation of this part of the device issimilar to the operation of a typewriter when the paper is insertedbetween the roll.-

The paper 21 after it passes between the guide plates 35 and 36 movesabout the idler 39 which may be fixedly positioned in the end plates oradjustably secured therein, as desired.

For cooperation with the idler 39 to perform the cutting or trimmingoperation I mount loosely on the shaft 27 the trimmer supportingbrackets 40 adapted to pivotally mount and and support the trimmers 41.These brackets 40 are shown as comprising two arms 42 which provide apair of bearings 43 for engagement with the said shaft 27 A single arm44 on said brackets projects clownwardly for rotatably supporting ashaft 45 of the cutters 41.

These cutters comprise essentially a body portion or hub 46 integrallysecured to the shafts 45 for rotation therewith and provided withapertures or bore holes in one of the faces 47 thereof for mounting ofthe cutter blade 48. This cutter blade 48 also provides apertures withinits face for the reception of bolts or other suitable fastening meanstherein for engagement with the apertures in the face of the bodyportion 46 for securing said cutters in place. Any other suitablemounting means might be utilized for securing these cutting blades 48 inposition. It will be noted that in this embodiment the body portions 46are of lesser radial extent than the blades 48.

For resiliently urging the cutters 41 into engagement with the paperpassing therebetween and the roll 39 I provide the resilient or springmeans shown at 49. These springs are stopped or fixed at one of theirextremities by engagement of said extremity with the plate 36 as appearsat 50. The other ends of these springs engage the portion 51 of thebracket 40 for normally urging the same about the shaft 27 toward theroll 39.

At the opposite side of the paste roller 15 for cooperation with theroller 39 for guiding the wall paper over the roll 15 for performing thepasting operation I provide an idler 52 which may be fixedly ournaled 1nthe plates 5 and 6. In this embodiment the roller 52 is adapted to beadjustably positioned in a slot 52 and retained therein by a retainingbearing means shown at 52 and which may be mounted on the end plates bymeans shown at 52. A milled screw 52 permits retention of the bearingmember 52 at desired points in slot 52 This idler 52 is particularlyformed to guide the paper from the machine by providing on the peripherythereof a series of ciroumferentially-extending corrugations comprisingthe ridges 53 and the hollows 54. By engagement with these ridges andthe hollows 54 the paper is secured in its proper path during withdrawalfrom the machine. This idler 52 cooperates with an oppositely disposedidler 55 in a manner that will be later described to further assureproper guiding of the paper during its exit from the machine. The roller55 is POST".

tioned by the aperture 56 from which the paper is withdrawn and over atrough 57 adapted to convey any paste or other adhesive matter droppingfrom the roll 55 back into the paste box 8. F or regulating the amountof paste adhering to the paste roll 15 during the pasting operation Iprovide a brush or scraper 58 supported by a bracket 59 for rotationwith a shaft 60 journaled in the end plates 5 and 6 in any suitablefashion. This brush may be adjusted for close or distant cooperationwith the paste on the roll 15 at the will of an operator by a lever 61fixedly mounted for rotation with the shaft 60. A resilient spring 62engageable between the end wall and the lever 61 serves to retain saidbrush in the adjusted position. Suitable stops 63 are provided as in thecase of lever 33 for limiting movement of this lever 61.

For allo 'ing access to the interior of the machine for permittingmeasurement of the width of the paper as well as for any other purposesdesired t 1e wall papering machine proper 4 is equipped with a door64-hinged as shown at 65 to the end plates 5 and 6 and secured in closedposition by any suitable latch means such as that indicated at 66. Abottom or base plate 67 being integral with or secured between the endplates 5 and 6 completes the housing structure of the wall paperiugmachine proper. This base or bottom plate 67' is provided with a cutawayportion. 68 which is adapted to be positioned behind the'paste box 8between the door 64 and the rear wall. of said paste box. It is throughthis cutaway portion 68 that the trimmed or cutawa portions 69 of thewall paper 21 exit upon the machine.

For supporting the wall papering machine in a suspended position whenthe machine is positioned for certain operations I provide a pair oflongitudinally extending rods 70 and 71 which extend between the endplates 5 and 6 and are secured therebetween in any desired manner. Theserods 70 and 71 pivotally mount thereon at each of their extremities setsof links 72 and 73 respectively. Pivotally interconnecting the links ofset 72 and 73 is a roller 74 which is utilized in one of the operationsto guide the paper and which may be further utilized as a bail member tobe used in the transportation of the wall papering machine proper.

The links 72 and 73 are provided with elongated slots engageable aboutthe rod 71 and a knurled or milled nut 71 secured to the ends of the rod71 for frictional engagement with the links 7 2 and 7 adjacent said slotto secure said links in variable adjusted positions as will be laterdescribed. Additional links 75 are pivotally connected to the roller 74.These links 75 provide eyelets 76 for the engagement therewith of bookmembers 77 used in the suspension of the device.

These hook members 77 may be of any suitable or desired construction,but as shown they comprise a rigid hooking member 78 and a resilientmember 79 cooperating therewith for performing the hooking operation inthe well known manner. The slot 80 provides means for engagement withstraps as will be described.

The wall papering machine suspension and mounting means 3 comprises apair of end plates 81 and 82 connected by rods 83 or other s Lin)suitable spacing means not shown and adapted to journal therein anautomatic reel 84. This automatic reel may be constructed in anysuitable fashion but is shown as being made in the form of an ordinaryshade roll having a spring (not shown) therein and having its shaftretained against movement in one direction by pawls adapted forengagement with the shaft 86 therein in a manner easily understood.

Suitable disks or collars 87 are provided at each extremity of the roll84 for engagement with straps 88 for securing the same against axialmovement along the roll. These straps 88 are connected to the hooks 77,as clearly shown in Figure 3 and are maintained in spaced relation bymeans of a bracing bar or rod 89.

For maintaining the wall papering machine suspension and mounting means3 in position during one of the operative positions of the device Imount on said suspension and mounting means 3 a plate 90 on which Iposition a block 91 having projecting therefrom a stud 92. This stud 92is secured in position in the block 91 by means of bolts or any othersuitable means. It carries a collar 93 having an aperture 94 therein.This collar 93 is provided for a purpose which will soon appear.

For retaining the stud 92 in its various positions to variably positionthe suspension and mounting member 3 during certain operations, saidstud 92 is provided with diametrically extending bores 95, 96, which areadapted for engagement with a bolt 97 which is equipped for release bythe latch means generally indicated at 98.

This latch means comprises a longitudinal- 1y extending member 99integral with said bolt and having positioned thereon a resilientcompression member 100 which has one end connected to the longitudinallyextending member 99 while the other abuts a stop or shoulder 101, asappears most clearly in Figure 3. A similarly formed stop or shoulder102 provides means for limiting outward movement of the bolt as well asaids in the guiding of said bolt during its operation. The operatinghandle 103 permits compression of the spring upon withdrawal of the boltby engagement of the operator with said handle or by other means.

The bolt-latch and associated members are mounted on an arm 104 which asappears most clearly in Figure 1 is adapted to project horizontally fromthe bracket support 2 to support the wall papering machine proper andits suspension and mounting means with respect to said bracket. This rod104 loosely engages through an eyelet 105 of a screw member 106 mountedon a collar 107 secured to the vertical post 108 which post isadjustably mounted in the clamping bracket. The rod 104 is supported bythe arms 109 which are pivotally secured to the post 108 and provide attheir outer extremities a saddle 110 which receives the rod 104 therein.It can be easily understood that these arms 109 and associated saddle110 and the screw member 106 provide a two point suspension for thehorizontally extending rod 104 permitting the same to he slidlongitudinally through said eyelet and said saddle for adjustablypositioning the wall-papering machine as desired.

When it is desired to position the machine as shown in Figure 2 forcertain operations, such as papering the ceiling, the locking slots 111in the suspension and mounting means 3 are utilized. These locking slots111 are adapted for engagement with the studs 112 or with the ends ofthe shafts 7 which may be constructed to project beyond the end plates 5and 6 for securing the wall papering machine proper in fixed position onthe suspension and mounting device 3. With the parts thus positioned theaperture 94 in the collar 93 is utilized for the reception of a bolt 113which is engageable through said collar and with the collar 107 forvariable positioning of said suspension and mounting member 3 about thepost 108, when desired by an operator. Adjustment of said suspension andmounting means is secured by means of the set screw 114 which projectsthrough said collar 107 and engages an aperture 115 in the post 108.

The clamping bracket is adapted for adjustably positioning the post 108by means of apertures (not shown) in said post, through which a latchmeans 116 is adapted to project. This latch means 116 is similar to thelatch means heretofore described in connection with the stud 92 and neednot be further described. The same is secured on top of the bracket 117in fixed relation.

This clamping bracket 117 as will appear from an examination of Figure10 is provided with clamping members 117 which clampingly engage a stepladder 1 or any other desired device on which it is wished to secure mydevice. These clamping members 117, as appears most clearly in Figures 2and 3, comprise a pair of horizontally extending jaws 118 and 119 withscrew-actuated clamp members 120 and 121 positioned in one of said jaws.These screw actuated clamp members 120 and 121 in cooperation with thejaws thus provide an ellicient clamping means for securing the entiredevice to any adaptable member as easily understood.

From the foregoing description, the use and operation of my device iseasily understood. When the operator desires to paper a wall hepositions the machine as shown in Figure 1 by clamping the clampingbracket 2 to any suitable support, such as the step ladder 1 insertingthe rod 104 through the saddle 110 and through the eyelet 105 of thescrew member 106 carried by the post 108. The wall papering machineproper 4 as shown in said figure, when the machine is set up in thisform for operation, is suspended by the straps 88 from the automaticreel 84.

The operator may, if de ired, by means of the la ch 103 release the stud92 and turn the suspension and mounting means 3 to a desired positionfor operation of the device.

He may further position the device by drawing down upon or releasing forelevation the wall papering machine proper a by means of the automaticreel.

When the machine is properly positioned for the wall-papering operationhe draws on the wall paper 21 manually or otherwise removes the samethrough the aperture 56. The paper during this operation is held undertension without backlashing or overtravel by means of the resilientlypressed roller 24 and the stationarily-positioned roller 23 and is cutor trimmed to the desired width by means of the cutters ll resilientlypressed into engagement with the paper as it passes about thestationarily-positioned idler 39. These cutters as heretofore set forthmay be adjusted to any desired width and may be thrown to the outerextremities of the shaft 27 out of engagement with the wall paperdesired. The trimmed paper then passes over the paste roller 15 whilethe trim 69 passes down through the aperture 68 and out of the machine.After the application of the paste by the roller 15 the paper passes outof the apertures 56 of the machine between the rollers 52 and 55. Theoperator has then only to apply the paper in the usual fashion manuallyor otherwise.

When the operator desires to apply wall paper to the ceiling hepositions the machine upon the top step of the step ladder as shown inFigure 2, as heretofore set forth, or upon any other suitable support.The stud 92 is inverted from the operative position shown in Figure 1with the collar 93 brought into engagement with the collar 107 which isstationarily positioned on the post 108. The stud 92 is integrallyconnected with the suspension and mounting means 3 and the same issupported on said stud 92 in the position shown in Figure 2. The wallpapering machine proper 4 is then placed on top of the invertedsuspension and mounting means 3 with the studs 112 or the ends of therods 7 whichever are utilized for the purpose being brought intoengagement with the locking slots 111. The links 7 2 and 73 having slotstherein for cooperation with the milled nuts 71 and 71 are thenadjustably positioned in the desired position such as that shown inFigure 2. Then s0 positioned the roll 74 which pivotally mounts thelinks, provides means over which the, paper may pass to bring the sameintofengagement with the ceiling, as shown in Figure 2.

= Theoperator may adj'ustably position the machine about the post 108 bymeans of the set screw 114i engageable through the collar 107'on saidshaft 108. I The machine may be further adjusted as to its io perativeposition by means of the latch 1l6 as heretofore set forth in connectionwith 7 the .bperative position shown in Figure 1.

The operator then draws the paper from the machineas described inconnection with the. other operative position about the roll-7 1ifdesilied, the same being trimmed and past-.

' V 8 During the positioning of the machine for various operations aswell as for transporta= ed by meanst. l

tion ofthe device the roll 74 may be used as agbail or handlefor manualengagement by theoperator for transportation purposes It isthus seenthat I have provided a wall papering machine which is adapted forpositioningin any desired place for operation by a user.

1 It is also seen that I provide a wall paper- 1. A wall paperingmachine comprising a member adapted to trim and apply the paste to thepaper, a suspension member adapted to position said member in elevatedand lowered positions during the operation, and means for adjustablypositioning said suspension means at the will of an operator.
